The throttle body is often where the TPS is installed (the housing that contains the throttle valve). If you have an idle that will hold for a bit, then drops off and dies, and if set higher, never drops off, that's a "hanging idle", and it's generally the result of a lean condition, which can be caused by improper idle circuit adjustment, contaminated jets, air leaks, or tight intake valves.

I found out mine was bad on one of my machines when I took it to the dyno. The quantity of gas to inject into the engine at any one time is precisely determined by the data that enables the throttle position sensor to monitor air entering the engine. The result is that the engine control unit (ECU) is unsure about how far to open the throttle valve, which makes the vehicle jerk or hesitate when it is being driven. will just "looping" it to bypass it resolve the issue like on the old blasters clutches? My dad just got his new yfz a few days ago. With no other 450-class quad . My mildly modded practice quad was not noticeable in riding, other than it didn't stumble at high rpm's anymore.
